Relating to or describing people or things that are native to a particular place from ancient times.
Derived from autochthon with the suffix -al to create an adjective form. This adjectival version maintains the same Greek roots (autos + chthon) but allows the concept to modify nouns.
This is the adjective version of autochthon, but it's rarely used compared to 'autochthonous'—language has a way of preferring one form over another even when multiple options exist. It's like how we say 'indigenous' more often than 'indigenal,' even though both could work.
